The relationship between patient-specific factors and functional progression of COVID-19 survivors admitted to an inpatient rehabilitation facility.

BACKGROUND: Survivors of hospitalization for severe acute COVID-19 infection faced significant functional impairments necessitating discharge to inpatient rehabilitation facilities (IRFs) for intensive rehabilitation prior to discharge home. There remains a lack of large cohort studies of the functional outcomes of patients admitted to IRFs with COVID-19-related impairments and the relationship to patient-specific factors. OBJECTIVE: To characterize functional outcomes of patients admitted to IRFs for COVID-19-related debility and to investigate associations between functional outcomes and patient-specific factors. DESIGN: Multisite retrospective cohort study. SETTING: Multiple IRFs in a large urban city. PARTICIPANTS: Adult patients admitted to IRFs for rehabilitation after hospitalization for acute COVID-19 infection. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Primary outcomes included change in GG Self-Care and Mobility Activities subscales and Functional Independence Measure scores from admission to discharge from inpatient rehabilitation. Linear regression analysis was used to relate functional changes to demographic, medical, and hospitalization-specific factors. Secondary outcomes included discharge destination from the IRF. RESULTS: The analysis included n = 362 patients admitted to IRFs for COVID-19-related rehabilitation needs. This cohort showed significant improvements in mobility, self-care, and cognition congregate scores (216.0%, 174.3%, 117.6% respectively). Patient-specific factors associated with functional improvement, included age, body mass index, premorbid employment status, history of diabetes and cardiac disease and medications received in acute care, and muscle strength upon admission to IRF. CONCLUSIONS: Patients admitted to inpatient rehabilitation for COVID-19-related functional deficits made significant functional improvements in mobility, self-care, and cognition. Many significant associations were found between patient-specific factors and functional improvement, which support further investigation of these factors as possible predictors of functional improvement in an IRF for COVID-19-related deficits.

Social determinants of health and COVID-19 recovery after inpatient rehabilitation.

BACKGROUND: Neighborhoods with more social determinants of health (SDOH) risk factors have higher rates of infectivity, morbidity, and mortality from COVID-19. Patients with severe COVID-19 infection can have long-term functional deficits leading to lower quality of life (QoL) and independence measures. Research shows that these patients benefit greatly from inpatient rehabilitation facilities (IRF) admission, but there remains a lack of studies investigating long-term benefits of rehabilitation once patients are returned to their home environment. OBJECTIVE: To determine SDOH factors related to long-term independence and QoL of COVID-19 patients after IRF stay. DESIGN: Multisite cross-sectional survey. SETTING: Two urban IRFs. MAIN OUTCOME MEASURES: Primary outcome measures were Post-COVID Functional Status Scale (PCFS) and Short Form-36 (SF-36) scores. Secondary outcomes were quality indicator (QI) scores while at IRF and a health care access questionnaire. Results were analyzed using analysis of variance and multivariate logistic regression analyses. RESULTS: Participants (n = 48) who were greater than 1 year post-IRF stay for severe COVID-19 were enrolled in the study. Higher SF-36 scores were associated with male gender (p = .002), higher income (≥$70,000, p = .004), and living in the city (p = .046). Similarly, patients who were of the male gender (p = .004) and had higher income (≥$70,000, p = .04) had a greater odds of a 0 or 1 on the PCFS. Age was not associated with differences. Women were more likely to seek follow-up care (p = .014). Those who sought follow-up care reported lower SF-36 overall and emotional wellness scores, p = .041 and p = .007, respectively. Commonly reported barriers to health care access were financial and time constraints. CONCLUSIONS: Patients with SDOH risk factors need to be supported in the outpatient setting to maintain functional gains made during IRF stays. Female gender, income, and urban setting are potential predictors for long-term QoL and independence deficits after rehabilitation for COVID-19 infection. Low emotional wellness is an indicator for patients to seek out care as far out as 1 year from their rehabilitation stay.

Recording antimicrobial use on Irish dairy farms: Barriers and facilitators to using technology and sharing data.

Antimicrobial use (AMU) data are essential to monitor the effect of AMU reduction strategies in animal health. The use of technology and herd recording software to record AMU will be vital to scale the collation of these data in the future. The aim of this study was to determine the barriers and facilitators to Irish dairy farmers recording their AMU using a herd recording software and sharing AMU data. Thirty-three Irish dairy farmers involved in a study on AMU monitoring were asked to record their AMU using a herd recording software over a 12-mo period. At the end of the 12-mo period, 10 of these farmers were selected to take part in semi-structured interviews exploring their opinions on recording AMU, the use of herd recording software, and sharing AMU data. Interviews were transcribed and qualitatively analyzed using inductive thematic analysis. Several barriers and facilitators to farmers recording their AMU using a herd recording software and sharing AMU data were identified. Barriers included the age and generation of the farmer, farm infrastructure, a lack of training and education, a lack of knowledge around the benefits of digital data, a lack of incentive to digitize records, and a fear of repercussions. Facilitators identified by the farmers included the benefits of having instantly available data for making herd management decisions, reduced paperwork, increased organization for inspections, and a potential positive effect on the image of the dairy industry. To increase the uptake of new technology to record AMU at farm-level, farmers will need support in terms of education and training around the software available to them and reassurance around the perceived risks of repercussions with sharing data in a digital format.

A Brief Intervention in Primary Care to Improve Parents' Discipline Practices and Reach Other Caregivers.

Parents (N = 599) of 6-month-old to 10-year-old children were given a handbook intervention that educates about healthy discipline in a pediatric clinic serving low-income families in Nashville, Tennessee. A research assistant spent approximately 1 minute introducing the intervention. A total of 440 parents (73.4%) responded to a follow-up survey 2 to 4 months later. Most parents (88%) who completed the follow-up survey had read at least part of the handbook. Of parents who received the handbook, 63% reported that the handbook helped them discipline their children. Half of parents reported specific changes they made because of the handbook. The most frequently reported changes were more talking/explaining/communicating (25%), more redirecting (7.8%), more patience/listening (6.0%), less anger/yelling (10.8%), and less spanking (7.5%). 42% of parents reported that they shared the handbook with other caregivers, friends, relatives, and children. A brief clinic intervention improves parents' discipline practices and reaches other caregivers.

PD-1 defines a distinct, functional, tissue-adapted state in Vδ1+ T cells with implications for cancer immunotherapy.

Checkpoint inhibition (CPI), particularly that targeting the inhibitory coreceptor programmed cell death protein 1 (PD-1), has transformed oncology. Although CPI can derepress cancer (neo)antigen-specific αß T cells that ordinarily show PD-1-dependent exhaustion, it can also be efficacious against cancers evading αß T cell recognition. In such settings, γδ T cells have been implicated, but the functional relevance of PD-1 expression by these cells is unclear. Here we demonstrate that intratumoral TRDV1 transcripts (encoding the TCRδ chain of Vδ1+ γδ T cells) predict anti-PD-1 CPI response in patients with melanoma, particularly those harboring below average neoantigens. Moreover, using a protocol yielding substantial numbers of tissue-derived Vδ1+ cells, we show that PD-1+Vδ1+ cells display a transcriptomic program similar to, but distinct from, the canonical exhaustion program of colocated PD-1+CD8+ αß T cells. In particular, PD-1+Vδ1+ cells retained effector responses to TCR signaling that were inhibitable by PD-1 engagement and derepressed by CPI.

Influence of donor point modifications on the assembly of chalcogen-bonded organic frameworks.

Incremental, single-atom substitutions of Se-based chalcogen bond (Ch-bond) donors with stronger donating Te centers were implemented in two new triptycene tris(1,2,5-chalcogenadiazole) tectons. The appreciably more favorable Ch-bonding ability of the Te-based donors promotes assembly of low-density networks and more stable Ch-bonded organic frameworks (ChOFs).

The potassium channel subunit KV1.8 (Kcna10) is essential for the distinctive outwardly rectifying conductances of type I and II vestibular hair cells.

In amniotes, head motions and tilt are detected by two types of vestibular hair cells (HCs) with strikingly different morphology and physiology. Mature type I HCs express a large and very unusual potassium conductance, gK,L, which activates negative to resting potential, confers very negative resting potentials and low input resistances, and enhances an unusual non-quantal transmission from type I cells onto their calyceal afferent terminals. Following clues pointing to KV1.8 (KCNA10) in the Shaker K channel family as a candidate gK,L subunit, we compared whole-cell voltage-dependent currents from utricular hair cells of KV1.8-null mice and littermate controls. We found that KV1.8 is necessary not just for gK,L but also for fast-inactivating and delayed rectifier currents in type II HCs, which activate positive to resting potential. The distinct properties of the three KV1.8-dependent conductances may reflect different mixing with other KV1 subunits, such as KV1.4 (KCNA4). In KV1.8-null HCs of both types, residual outwardly rectifying conductances include KV7 (KCNQ) channels. Current clamp records show that in both HC types, KV1.8-dependent conductances increase the speed and damping of voltage responses. Features that speed up vestibular receptor potentials and non-quantal afferent transmission may have helped stabilize locomotion as tetrapods moved from water to land.

Disability terminology: the use of "disability," "disorder," and "illness" in academic writing.

PURPOSE: The ways in which words are used to describe and discuss people with disabilities has long been an area of social concern. Previous research has demonstrated that language can overtly and subtly influence cognitions and perceptions of individuals, but there is less research on how language relates to perceptions of individuals with disabilities. MATERIALS AND METHODS: A content analysis of 236 peer-reviewed articles was performed to explore differences in the frequency of the use of "disability," "disorder," and "illness" in academic articles related to eight common conditions: deafness, blindness, multiple sclerosis, quadriplegia, anxiety, depression, schizophrenia, and addiction. RESULTS: Results indicated that there were differences in how disability language was used by academic writers. Specifically, "disability" appeared in the writing more frequently in articles related to physical disabilities, "disorder" appeared most frequently in articles related to anxiety and depression, and "illness" appeared most frequently in articles related to schizophrenia. CONCLUSIONS: This observed difference in frequency use could reflect differences in the context and meaning of the use of these conditions. Suggestions for future research are discussed.

The way individuals write and talk about conditions may indicate the way they think about the conditions.When compared to articles written about physical conditions, the term "disability" is used less by academic writers than when discussing mental conditions.This suggests that academic writers may view mental conditions as less "prototypical" disabilities (compared to physical conditions).Careful consideration should be given to the language used when discussing all types of disabilities.When writers, media professionals, policymakers, and the public are educated on the diverse range of conditions and the unique challenges they present to individuals, only then can rehabilitation be truly comprehensive and effective.

Patient-Reported Outcome Measurement Information System Measures for Proximal Interphalangeal Joint Arthrodesis in Lesser Toe Deformities.

Although hammertoe (HT) is a common complaint among foot patients, there is little consensus on the best surgical approach for correction. These authors hypothesized that the use of a headless intramedullary screw across both the proximal interphalangeal joint (PIPJ) and distal interphalangeal joint (DIPJ) would decrease many post-surgical complications, such as infection, pain, and mallet toe deformity, found in traditional HT corrective surgical techniques. In this retrospective cohort study, N = 163 adult patients who had undergone DIPJ/PIPJ arthrodesis for HT correction at least 1 year prior to the study were identified. One hundred fifty-nine patients were contacted through REDCap to complete Patient-Reported Outcome Measurement Information System (PROMIS) physical function (PF) and pain interference (PI). Demographic, radiographic, and follow-up data were taken from the electronic medical record (EMR). Analysis was completed with Microsoft Excel; PROMIS PF and PI measures for the 32-person cohort were 45.65 ± 8.26 and 51.65 ± 9.01, respectively. The PF and PI measures had a statistically significant correlation (R2 = 0.71). The 163-person cohort had an overall revision rate of 6.75%, or 11 patients, and an infection rate of 1.23%. This procedure had lower rates of residual pain, infection, mallet toe deformity, and reoperation when compared with current techniques. This study supports the safety and viability of PIPJ/DIPJ arthrodesis using a headless screw for HT correction.Levels of Evidence: Level III Retrospective Cohort Study.

Olfactory drug delivery with intranasal sprays after nasal midvault reconstruction.

Conductive olfaction and nose to brain drug delivery are important processes that remain limited by inadequate odorant or drug delivery to the olfactory airspace. Primary challenges include anatomic barriers and poor targeting to the olfactory region. This study uses computational fluid dynamics to investigate the effects of nasal midvault surgery on olfactory drug delivery with intranasal sprays. Soft tissue elevation, spreader flaps, and spreader grafts were performed on two fresh cadaveric specimens, using computed tomography for airway reconstruction. Nasal airflow and drug particle transport simulations were performed under these conditions: inhalation rate (15, 30 L/min), spray velocity (1, 5, 10 m/s), spray location (top, bottom, center, medial, lateral), head position (upright, supine, forward, backward), and particle size (1-100 µm). Simulation results were used to calculate drug particle deposition to the olfactory airspaces and bulbs. Total olfactory deposition was < 5% but attained a maximum of 36.33% when sorted by particle size. There was no association between nasal midvault surgery and olfactory deposition. No single parameter or technique demonstrated superior olfactory deposition, but smaller particle size, slower spray velocity, and higher inhalation rate tended to optimize olfactory deposition, providing important implications for future intranasal spray and drug design to target the olfactory airspace.

Clinical features and outcomes of hospitalised patients with COVID-19 and Parkinsonian disorders: A multicentre UK-based study.

BACKGROUND: Parkinson's disease has been identified as a risk factor for severe Coronavirus disease 2019 (COVID-19) outcomes. However, whether the significant high risk of death from COVID-19 in people with Parkinson's disease is specific to the disease itself or driven by other concomitant and known risk factors such as comorbidities, age, and frailty remains unclear. OBJECTIVE: To investigate clinical profiles and outcomes of people with Parkinson's disease and atypical parkinsonian syndromes who tested positive for COVID-19 in the hospital setting in a multicentre UK-based study. METHODS: A retrospective cohort study of Parkinson's disease patients with a positive SARS-CoV-2 test admitted to hospital between February 2020 and July 2021. An online survey was used to collect data from clinical care records, recording patient, Parkinson's disease and COVID-19 characteristics. Associations with time-to-mortality and severe outcomes were analysed using either the Cox proportional hazards model or logistic regression models, as appropriate. RESULTS: Data from 552 admissions were collected: 365 (66%) male; median (inter-quartile range) age 80 (74-85) years. The 34-day all-cause mortality rate was 38.4%; male sex, increased age and frailty, Parkinson's dementia syndrome, requirement for respiratory support and no vaccination were associated with increased mortality risk. Community-acquired COVID-19 and co-morbid chronic neurological disorder were associated with increased odds of requiring respiratory support. Hospital-acquired COVID-19 and delirium were associated with requiring an increase in care level post-discharge. CONCLUSIONS: This first, multicentre, UK-based study on people with Parkinson's disease or atypical parkinsonian syndromes, hospitalised with COVID-19, adds and expands previous findings on clinical profiles and outcomes in this population.

Behaviour change interventions for responsible antimicrobial use on farms.

BACKGROUND: In the coming years, major governance changes in the form of policy directives and regulations will catalyse major top-down change with respect to animal health on European farms in an effort to combat the OneHealth threat of antimicrobial resistance. This top-down approach must be met with bottom-up strategies to ensure target actors (namely, farmers and vets) are supported and motivated to change their practices, thus, avoiding unintended consequences of forced change. Although much behavioural research has explored the factors influencing antimicrobial practices on farms, a gap exists translating these findings into evidence-based behaviour change interventions that can be put into practice. The current study aims to fill this gap. It provides insights into identifying, understanding, and changing the behaviours of farmers and veterinarians with respect to the responsible use of antimicrobials in farming. RESULTS: Through an inter-disciplinary and multi-actor approach, the study combines scientific knowledge from the behavioural sciences and animal health sciences, coupled with tacit knowledge from a co-design, participatory approach to recommend seven behaviour change interventions that can help to support good practices amongst farmers and vets, with respect to animal health, and reduce the use of antimicrobials on farms. The behaviour change interventions include message framing; OneHealth awareness campaign; specialised communications training; on-farm visual prompts and tools; social support strategies (for both farmers and vets); and antimicrobial use monitoring. The study details each intervention with respect to their evidence base and scientific concept, grounded in behavioural science, along with stakeholder feedback on design and delivery of the interventions. CONCLUSIONS: These behaviour change interventions can be taken, adapted, and put into practice by the agri-food community to support good animal health practices and responsible antimicrobial use on farms.

Rapid assembly of SARS-CoV-2 genomes reveals attenuation of the Omicron BA.1 variant through NSP6.

Although the SARS-CoV-2 Omicron variant (BA.1) spread rapidly across the world and effectively evaded immune responses, its viral fitness in cell and animal models was reduced. The precise nature of this attenuation remains unknown as generating replication-competent viral genomes is challenging because of the length of the viral genome (~30 kb). Here, we present a plasmid-based viral genome assembly and rescue strategy (pGLUE) that constructs complete infectious viruses or noninfectious subgenomic replicons in a single ligation reaction with >80% efficiency. Fully sequenced replicons and infectious viral stocks can be generated in 1 and 3 weeks, respectively. By testing a series of naturally occurring viruses as well as Delta-Omicron chimeric replicons, we show that Omicron nonstructural protein 6 harbors critical attenuating mutations, which dampen viral RNA replication and reduce lipid droplet consumption. Thus, pGLUE overcomes remaining barriers to broadly study SARS-CoV-2 replication and reveals deficits in nonstructural protein function underlying Omicron attenuation.

Purkinje cell dopaminergic inputs to astrocytes regulate cerebellar-dependent behavior.

Dopamine has a significant role in motor and cognitive function. The dopaminergic pathways originating from the midbrain have received the most attention; however, the relevance of the cerebellar dopaminergic system is largely undiscovered. Here, we show that the major cerebellar astrocyte type Bergmann glial cells express D1 receptors. Dopamine can be synthesized in Purkinje cells by cytochrome P450 and released in an activity-dependent fashion. We demonstrate that activation of D1 receptors induces membrane depolarization and Ca2+ release from the internal store. These astrocytic activities in turn modify Purkinje cell output by altering its excitatory and inhibitory synaptic input. Lastly, we show that conditional knockout of D1 receptors in Bergmann glial cells results in decreased locomotor activity and impaired social activity. These results contribute to the understanding of the molecular, cellular, and circuit mechanisms underlying dopamine function in the cerebellum, revealing a critical role for the cerebellar dopaminergic system in motor and social behavior.

Intranasal Spray Characteristics for Best Drug Delivery in Patients With Chronic Rhinosinusitis.

OBJECTIVES: To determine parameter combinations for effective drug delivery of intranasal spray steroids to the ostiomeatal complex (OMC) and maxillary sinus (MS) in patients with chronic rhinosinusitis (CRS). METHODS: Each patient's sinonasal cavity was reconstructed from computed tomography scans. Intranasal airflow and drug particle transport were simulated using computational fluid dynamic modeling. Airflow simulations were performed at 15 Pascal inhalation pressure. Intranasal spray particles of 1-100 µm were simulated at release speeds of 1, 5, and 10 m/s from 6 release locations (Bottom, Center, Top, Lateral, Lateral-Bottom, and Lateral-Top) at a nozzle insertion depth of 15 mm. Drug delivery simulations were performed in the head tilted forward position. RESULTS: Maximal OMC deposition was 0.78%-12.44%, while maximal MS deposition was 0.02%-1.03% across all simulations. In general, particles between 6 and 10 µm had the best OMC (at 1 m/s particle velocity) and MS (at 10 m/s particle velocity) deposition. Particles ranging from 21 to 30 µm also had superior OMC deposition. The lateral and lateral-top spray release locations produced maximum OMC deposition, but no one release location demonstrated an increase in MS deposition. CONCLUSION: This preliminary study suggests that it is challenging to determine a common set of intranasal spray parameter combinations for effective drug delivery to the OMC and MSs. Although drug particle size and spray particle velocity seem to impact particle deposition patterns, spray release location appears to vary with anatomical differences between subjects, particularly when the MS is the target location for particle deposition.

Impact of maternal cytomegalovirus seroconversion on newborn and childhood hearing loss.

Objectives/hypothesis: The objective of this study is to describe long-term hearing outcomes in infants born to mothers with a known cytomegalovirus (CMV) positivity who were not tested for congenital CMV. Study type: Clinical research study. Design: Retrospective cohort study. Methods: Retrospective chart review was performed for mothers seropositive to CMV. Mother-infant dyads (130) were identified between January 1, 2013 and January 1, 2017. Outcomes data was collected through June 1, 2020. Demographics, risk factors for hearing loss, evidence of CMV infection, other causes of hearing loss, need for speech therapy services, and results of all hearing tests were collected. Results: All 130 infants were asymptomatic and 5 were tested for congenital CMV. Five were negative for CMV and excluded from analyses. Of the remaining 125, only 1 had low-viral avidity IgG antibodies. None had IgM antibodies. Four children (3.2%) had hearing loss at last audiogram and one child had delayed onset SNHL due to an enlarged vestibular aqueduct. Speech therapy for communication was required for 33 children (26.4%). Conclusions: Knowledge of maternal perinatal CMV status can allow for education about possible sequelae of cCMV, as well as trigger an alert for testing babies born to mothers with low-viral avidity IgG during the first trimester, when the risk of vertical transmission is highest. Also, babies born to CMV positive mothers may be more at risk for communication delays necessitating intervention. Studies focusing on the impact of maternal CMV related to childhood communication deficits could elucidate any direct relationships.

If You Pay, Will They Come? Evaluating the Impact of Subsidies on Cessation Outcomes in the Walk or Run to Quit Program.

Introduction: Exercise interventions may assist smoking cessation attempts. One such publicly available 10-week program, Walk or Run to Quit (WRTQ), demonstrated success in smoking cessation and physical activity (PA) outcomes. However, initial WRTQ participants (2016-2017) were fairly homogenous in their demographic profile. To increase diversity, subsidies for participation were offered in 2018. This study assessed how the subsidies affected participant demographics, running frequency, smoking cessation, intention to quit, and program attendance and completion. Methods: The $70 registration fee was subsidized for 41% of participants in 2018. A pre-postdesign was used, with participants completing surveys on their demographics and smoking and physical activity behaviours. Descriptive statistics compared the year subsidies were available (2018) and unsubsidized years (2016-2017) and subsidized and unsubsidized participants' data from 2018. Results: The 2018 participants had lower average attendance and program completion rates compared to 2016-2017 and no statistically significant differences in demographics or smoking cessation and PA outcomes. There were no differences in smoking cessation, run frequency, or demographic variables between the subsidized and unsubsidized participants in 2018. Conclusions: Offering subsidies did not diversify the participant profile. Subsidies did not have a negative impact on attendance nor primary outcomes. Subsidies may not have addressed barriers that prevented a more diverse sample from participating in WRTQ, such as program location, timing, and design. Equitable access to smoking cessation programs remains essential. As subsidies may play a role in reducing financial barriers disproportionately faced by marginalized groups, the implementation of, and recruitment for, such subsidized programs requires further investigation.

Diverse Roles of the Exon Junction Complex Factors in the Cell Cycle, Cancer, and Neurodevelopmental Disorders-Potential for Therapeutic Targeting.

The exon junction complex (EJC) plays a crucial role in regulating gene expression at the levels of alternative splicing, translation, mRNA localization, and nonsense-mediated decay (NMD). The EJC is comprised of three core proteins: RNA-binding motif 8A (RBM8A), Mago homolog (MAGOH), eukaryotic initiation factor 4A3 (eIF4A3), and a peripheral EJC factor, metastatic lymph node 51 (MLN51), in addition to other peripheral factors whose structural integration is activity-dependent. The physiological and mechanistic roles of the EJC in contribution to molecular, cellular, and organismal level function continue to be explored for potential insights into genetic or pathological dysfunction. The EJC's specific role in the cell cycle and its implications in cancer and neurodevelopmental disorders prompt enhanced investigation of the EJC as a potential target for these diseases. In this review, we highlight the current understanding of the EJC's position in the cell cycle, its relation to cancer and developmental diseases, and potential avenues for therapeutic targeting.
